SPECIFICATION forming part of Letters PatentNo. 729,780, dated June 2,1903.

Application filed July 23, 1902. Serial No. fiance. (N0 model.)

To all 1072 0711, it may concern:

Be it known that I, THOMAS A. lVIA'ITHEWS,

a citizen of the United States, residing at Nashville, Davidson county,Tennessee, have invented certain new and useful ImprOVeQ. ments inLamp-Burners, of which the foly lowing is a specification.

My invention relates to that class of bu-rn-- ers with which chimneysare employed.

The objects of my inventionare to provide an improved chimney-holdingmechanism adapted to hold chimneys which vary in diameter, also toprovide a chimney-holderhinged so as to swing out with the chimneybeyond the burner proper and leave the wicktube fully exposed fortrimming the .wick,

cleaning, &c.', also to provide a simple and eifective means for lockingthe chimney-car;

rying section to the burner-carrying section. These objects I accomplishby the construction shown in the accompanying drawings, in which-'-Figure 1 is a perspective of a burner with Fig. 2 is a simimyimprovements applied. lar view with the chimney-holder swung out. Fig. 3is adetail perspective of the chimneyholding fingers with their carryingand re taining rings. latch mechanism.

A is the burner proper, provided, as usual, with awick-tube a andperforated air-supply plate a.

B is the cone provided around its base beyond the periphery of the platea with a Fig. a is a detail view of the perforated horizontal flange I),having a series c the two members of the fingers are curved,

as at c, toform clamping-surfaces to yield and engage the chimney. Thefingers Gare preferably pivoted on a carrying-ring D, which passesthrough apertures in their lower ends. (See Fig. 3.) The fingers Carepassed up through the slots b,'with the ring D within the dependingflange b whereupon certain of. the cars 19 are bent inwardly and,upwardly around the ring D (see Fig. 2) to secure it in place.

E is a retaining-ring secured to the outer side of flange b by bendingcertain of the ears 6 upwardly and inwardly around it. (See Fig. 1.)Thering E is provided with upwardly-projecting spring-fingers E, whichbear at their upper ends against the outer sides of the chimney-holdingfingers (J and press the same inwardly against the inner ends of theslots 0 The fingers 0, therefore, have a yielding pivotalmovement, andso chimneys which vary somewhat at the base will readily fit in the saidforked fingers. These improvements are of course adapted to burnerswherein the cone and chimneyholder have noswinging movement, but arefixed. I prefer aswinging chimney-holder, however, and, as shown in Fig.2, I hinge the cone B by a hinge a at the inner edge of the perforatedflange b to the outer edge of the perforated plate a, and by this meansthe chimney-holder as a whole may be swung outwardly at right angles tothe burner proper, and the then lower edge of the flange b b will engagethe side of the burner and hold the chimney-holder from swinginclownwardly.

F designates the latch formed of a single length of spring-wire bent atright angles, as

shown, to form the two members ff, at the junction of which the wire isbent upon itself to form the finger-piece f The spring-retaining memberf extends along the inner side of the flange 12 to which it is securedby passing its bent outer end f through an aperture in the said flangeand upsetting or heading said end f. The finger-piece) proj ecis throughan opening in the flange b and the inner end of the member f is providedwith a depending hook or arm f, which en= gages an upturned lip a on theedge of the perforated plate a at a point opposite the hinge (L Thesliding member f is guided by a loop f on the lower side of the horizon=tal flange b. By pressing the finger-piece f inwardly against the actionof the spring member f the latch will be released, and the holder andchimney may be swung out at right angles, as in Fig. 2.

What I claim is 1. The combination with a lamp-burner, of a plurality offorked chimney-holding fingers pivotally connected thereto and ayielding retaining means pressing said fingers inwardly.

2. The combination with a lamp-burner, of a plurality of pivoted forkedchimney-holdin g fingers thereon and spring-fingers bearing against theouter sides of said forked fingers.

3. The combination with a lamp-burner hav-,

ing a series of slots, of a series of forked chimney-holding fingersextending up throughsaid slots, a ring secured to the burner and towhich all of said fingers are pivoted and a series of spring-fingersbearing against the outer sides of the forked fingers.

4. The combination with a lamp-bu rner hava series of slots, of a seriesof forked chimneyholding fingers extending up through said slots, andapertured at their lower ends, a ring secured to the burner, passedthrough the said apertures and forming the axis of all of said fingers,and a second ring secured to the burner and having a series of yieldingfingers bearing against the outer sides of the forked fingers.

5. In a lain p-burner, a chimney-holder comprising the cone having atits base an outwardlyprojecting slotted flange, a second flangedepending from the periphery of the first flange and having a series ofdepending ears, two rings around which certain of the ears are bent,forked chimney-holding fingers pivoted at their lower ends on one ofsaid rings and extending up through said slots and yielding fingersextending up from the other ring and bearing against the outer sides ofthe forked fingers.

(5. The combination with theburner proper, having a catch a, of thechimneyholder hinged to the burner opposite said catch and provided witha circular horizontal flange and an annular flange dependingtherefrom;the horizontal flange lying beyond the top of the burner, an angularlatch F having a springattaching arm secured to the inner side of saidannular flange, a latch-arm guided on the under side of the saidhorizontal flange and terminating at its inner end in a depending arm orhook to engage the catch a and a finger-piece f at the junction of themembers f, f and projecting through an aperture in said annular flange,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

THOMAS A. MATTHEWS.
